Thanks for playing! The video was very useful.
About the rotation hold : I I'll include it in the options, perhaps something like "camera drag : hold/toggle" for left click.
Should have clamped vertical view to less than 90, because that threw you off on the "Oblique" tutorial, where the point was to show that the dudes can meet when on differently oriented faces (and that the dude that is moving absorbs the one that is still).
As for inconsistent links, the small windowed size might make precision aiming harder (too lazy to options menu in time), but I'll try to increase the grace radius for links.
Also there is a level editor, it only shows the button for it when "custom" levels are selected, should probably make that clearer.
